TCL

Brian Harrison

Hello,

Is there a proper way to load a dynamically loadable TCL extension in encounter?

example:  www.swig.org/tutorial.html

When I complile the above example and try to load it within encounter I get:

couldn't load file "./example.so": ./example.so: cannot open shared object file: No such file or directory

This works fine within a normal tcl shell.

On a previous project I wrote crude placement algorithm in TCL using encounter commands.  This was done to overcome limitations with encounter clock tree synthesis with IBM ASIC methodology.   The algorithm worked great, but was slow since being in TCL.   I could speed this up in C/C++ using SWIG to create the TCL wrapper.  

Any help?

Best Regards,

Brian

  •  The "No such file or directory" seems suspect but it's weird that it works in stock Tcl.  I usually load all of my tcl packages (albeit, all have been straight Tcl) using packages.  Perhaps there's something wrong with your auto_path?  Are you loading these directly (using 'load') or via 'package require'?
